脱硝技术主要是将含氮的还原剂（尿素、液氮或氨水）喷入到温度850～1100℃ 烟气中，使其发生反应，脱硝NO 生成氮气和水。由于在一定温度范围及有氧气的情况下，含氮还原剂对NO 的还原具有选择性，因为反应中不需要催化剂，所以称为非催化还原法。主要设备有：储罐、泵、喷枪、管路、测控设备。
Denitration technology is mainly to inject reducing agent containing nitrogen (urea, liquid nitrogen or ammonia) into the flue gas whose temperature is 850 ~ 1100℃ to make them react to generate nitrogen and water. In a certain temperature range and the presence of oxygen, nitrogen reducing agent on the reduction of NO2 has selectivity, because the reaction does not need the catalyst, so called that non catalytic reduction method. Main equipment are storage tank, pump, spray gun, pipeline,test equipment.
工作原理 WORKING PRINCIPLE
1,Low investment costs,low operating costs and small area.
2, Simple system,short installation period .
3, Do not need to replace the lead fan, the boiler operation will not have a impact.
4, The process is a clean technology, there is no pollution and no twice pollution.
5, Denitration efficiency is 40 ~ 70%.
